Next week I will present the new work on Fable Beam at Oslo F# Meetup 💫 #fsharp #fablecompiler

11 years ago I’ve made first commit on the project that would later be known as Ionide. A lot has changed over all those years, but one thing remains - the biggest value of the project has been meeting awesome people from F# community, many of whom I’m proud to call friends. #fsharp

🚀 Fable 5.0.0-alpha.14 is out! This one has a big focus on Python and adding support for Nullness to Fable (both your project and dependencies needs to be written with nullness in mind for it to work) To benefit from all the new features you need to use Fable.Core beta too #fsharp #fablecompiler

Thanks to recent contribution EasyBuild.FileSystemProvider reached stable release. If you are upgrading you probably want to replace RelativeFileSystem with AbsoluteFileSystem to get the same behavior as before. I didn't use the right naming from the start 🙈 #fsharp

🦾 Major hat tip to @compositional-it.com for advancing it and for all of the contributors like @mangelmaxime.bsky.social and many others for Fable. We love @dzoukr.cz 's SAFEr stack and are lifting its opinions for our static site generator (and are building an Oxpecker back-end option for it). 💙

It has been a while since we announce a new release, but don't worry we have been cooking a lot. Here are the Changelogs for Fable 5.0.0-alpha 10 & 11 #fsharp #fablecompiler

Happy new year! 🎉 To start this new year, we have a new alpha version of Fable 5. #fsharp #fablecompiler

Authoring Fable package has never been easier. You can use a ready to use repo template or setup Fable.Package.SDK yourself if you don't want all the things coming with Glutinum.Template. Check out the updated guide at: fable.io/docs/your-fa... #fsharp #fablecompiler

Well, it's been more than 3 years 😵, but I am pleased to share that I have, once again, blogged a thing, as part of the 2024 #fsharp Advent Calendar: paul.blasuc.ci/posts/fault-... #FsAdvent #dotnet

Work for supporting Feliz style output has started in Glutinum! This is not yet available publicly but hopefully, I will be able to soon release something. #fsharp #fablecompiler

This week EasyBuild.Tools got several releases improving existing APIs and adding new CLI tools. #fsharp #dotnet

Glutinum 0.12.0 is available. This version focus on adding more UtilityType support and Iterable. Check the full changelog for more details and examples: github.com/glutinum-org... #fsharp #fablecompiler

The EasyBuild ecosystem now supports `perf`, `build`, and `revert` commit types, aligning with the Angular conventional commit format - one of the most popular standard currently. Upgrade to the latest version if needed. #fsharp #dotnet

EasyBuild.Tools 2.0.0 is released with 2 new APIs for: - Updating package.json version - Retrieving the last version of a changelog file This is useful for projects who don't adhere to the automated EasyBuild ecosystem. #fsharp

While I was taking a few days off someone has been busy. So I can make my first Fable release announcement on Bluesky: Fable 4.24.0 is out 🎉 Thanks ncave for the work and all the people who reported an issue. #fsharp #fablecompiler

EasyBuild.ChangelogGen is available 🎉 This is a CLI tool automating Changelog generation based on your Git history using Conventional Commits. What's magic is its ability to compute the version number automatically for you! Learn more about it at: github.com/easybuild-or... #fsharp #dotnet

I needed documentation for some APIs I'm working on, so I tried using `details + summary` in markdown. It keeps things compact while making the APIs easy to browse. Not perfect, but for a small utility project, it works great! #fsharp

Glutinum 0.11.0 is out, this is another huge release. If you want the detailed changelog with examples, you can view it on Github: github.com/glutinum-org... #fsharp #fablecompiler
